Abstract
The utility model discloses a connection structure of a connecting rod and a crank throw. The connection structure comprises the connecting rod and the crank throw, one end of the connecting rod is connected with the crank throw through a semi-ring clamping structure, and a bearing rolling support with a holder is arranged between the connecting rod and the crank throw. The connection structure is simple in structure and reasonable in design, uses the bearing rolling support with the holder to replace a traditional bearing bush to serve as a friction piece, reduces manufacturing cost, converts sliding friction between the connecting rod and the crank throw into rolling friction, reduces coefficient of friction, reduces a frictional contact area, solves problems of excess temperature of lubricating oil and quick abrasion of parts caused by generation of heat caused by friction, and greatly improves mechanical transmission efficiency.
Description
Technical field
The utility model belongs to the mechanical transmission member technical field, particularly relates to the linkage structure of a kind of connecting rod and crank throw.
Background technique
In general, the two supports of bent axle is on frame, and an end of connecting rod is provided with mounting hole and is connected with crank throw, use the bearing shell of Babbitt as friction member between connecting rod and the crank throw, the other end of connecting rod and crosshead are hinged with bearing pin, and crosshead is installed in the interior die cavity of frame, can only do straight line motion.When bent axle rotated, three off-centre on the bent axle turned flexing axle central rotation, drove crosshead by connecting rod and did straight reciprocating motion.Can produce relative rotation between connecting rod, bearing shell, the crank throw, rub.Principle because of frictional heat, the heat temperature that produces can make lubricating oil temperature rising in whole pump component and the frame chamber by the metal transmission, the too high meeting of lubricating oil temperature causes lubrication failure, the component excess Temperature can cause parts wear to accelerate, to using effect and working life of pump all producing harmful effect.
The model utility content
It is high that the purpose of this utility model just provides a kind of machinery driving efficiency, the connecting rod that friction factor is little and the linkage structure of crank throw, thus solve the technical problem that the lubricating oil temperature that causes because of frictional heat is too high and parts wear is accelerated.
The purpose of this utility model realizes by following technical proposals:
The linkage structure of a kind of connecting rod and crank throw comprises connecting rod and crank throw, and an end of connecting rod adopts semi-ring clamp band type structure to be connected with crank throw, and the bearing element spare with retainer is set between connecting rod and crank throw.
As preferably, described bearing element spare with retainer is the loop configuration that is made of two semi-circular friction members.This structure is conducive to make and install.
As preferably, described bearing element spare is needle roller.
As preferably, described bearing element spare is ball.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, reasonable in design, employing has replaced traditional bearing shell as friction member with the bearing element spare of retainer, has reduced manufacture cost, changes the sliding friction between connecting rod and the crank throw into rolling friction, reduced friction factor, reduced the rubbing contact area, not only solved the problem that the lubricating oil temperature that causes because of frictional heat is too high and parts wear is accelerated, and greatly improved machinery driving efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is mounting structure schematic representation of the present utility model;
Fig. 3 is the utility model mounting structure cross-sectional view.
Embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
Embodiment one, such as Fig. 1, Fig. 2 and shown in Figure 3, the linkage structure of a kind of connecting rod and crank throw, comprise connecting rod 1 and crank throw 3, one end of connecting rod 1 is the mounting hole that semi-ring clamp band type structure forms, crank throw 3 is installed in this mounting hole, two semiorbicular needle rollers 2 with retainer is installed as friction member between connecting rod 1 and crank throw 3.
Crank throw 3, just form a floating bearing structure after linking together with needle roller 2, the connecting rod 1 of retainer, have the various performances of floating bearing.Connecting rod 1 is hinged with crosshead 4 usefulness bearing pins, and crosshead 4 is installed in the frame 5 interior die cavities, and when bent axle 6 rotated, three crank throws, 3 flexing axles, 6 central rotations on the bent axle 6 drove crosshead 4 by connecting rod 1 and do straight reciprocating motion.
Than bearing shell, friction mode is rolling friction with the needle roller 2 of retainer, and the rubbing contact area is little, machinery driving efficiency is high, therefore can reduce frictional heat than bearing shell as friction member, avoids lubrication failure, slow down parts wear, improve using effect and the working life of pump.
Embodiment two, and present embodiment and embodiment's one difference is, two semiorbicular balls with retainer are installed as friction member between connecting rod and crank throw.
Linkage structure of the present utility model can be used in widely with the matching used bearing bush structure of crankshaft type on, such as motor, diesel engine, automobile etc.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
